about ben gupta's story when i got a phone call just after his death from former president bill clinton. ben's father is an old friend of the clintons. >> what kind of a kid was he? >> a light shined out of him. that's all i can tell you. he grew up, he was big, strong, handsome, smart. and wanted to make something of his life. he was industrious, but he was normal. he liked to have a good time. he had -- i promise you that night, he had no idea that he was turning out the lights. none. and if it's true of him, it's got to be true of a lot of other people. >> he finds some solace from his son's death by funding programs that educate people about the dangers of misusing prescription drugs. and recently, he made a $1 million pledge to the clinton global initiative, to support the former president's new-found passion about this issue. >> he said, i have been very fortunate. and my son was worth $1 million. >> it's still hard to talk about. >> oh, it is, it is. >> do you think it ever won't be? >> no. i think about him all of the time. like in d.c. today, so i went walking on the gw campus.
